sadf: Add new output format: raw (part 1)
Add a new output format to sadf to display statistics saved in a binary
data file in raw format. Counters values are displayed "as is", without
trying to calculate an average value over the elapsed time interval.
This is something I have selfishly wanted to have for a long time now,
mainly for debugging purpose.
This first patch adds all the necessary global functions, and implements
the raw format only for CPU and task creation/system switching
statistics.
When a newly registered device (network interface or disk) was
supernumerary (i.e. there was no slot left in the list to store it), it
would take the place of another device in the list. This other device
would also appear as new and its counters would jump as if starting from
zero. This patch fixes that.

sar/mpstat: Allow selection of a range of IRQ/CPU
Update sar so that the user can now select a range of interrupts with

Keyword XALL is removed with option -I.
Keyword ALL selects all possible interrupts, including the sum of them.
Also update mpstat so that the user can select a range of processors
with option -P (in addition to selecting individual processors).

confused with the "ALL" keyword which selects all the CPUs of the

from #12 and following.
sar -P all,1 Select CPU #1 and the global average CPU value

sar: Improve cpuinfo read for POWER architecture
Currently CPU frequency is not being read properly on POWER archicture.
It shows the frequency as:

locales.
